[ Upstream commit ab107276607af90b13a5994997e19b7b9731e251 ]
Since termio interface is now obsolete, include/uapi/asm/ioctls.h has some constant macros referring to "struct termio", this caused build failure at userspace.
In file included from /usr/include/asm/ioctl.h:12, from /usr/include/asm/ioctls.h:5, from tst-ioctls.c:3: tst-ioctls.c: In function 'get_TCGETA': tst-ioctls.c:12:10: error: invalid application of 'sizeof' to incomplete type 'struct termio' 12 | return TCGETA; | ^~~~~~
Even though termios.h provides "struct termio", trying to juggle definitions around to make it compile could introduce regressions. So better to open code it.
